2) wants to download just one (or a few) file(s): right click / add to download list

3) wants to remove the remaining links: clicks the "broom" icon in the lower left corner

sadly, between 2) and 3) JD2 has switched to the download window. if the user does not recognize this, maybe because linkgrabber and download list look similar on a short glimpse, he/she deletes the whole "main" download list, especially when the "are you sure" dialog has been disabled.
